药品质量分析是药政、药检工作的重要环节之一,随着科学技术的迅速发展,新的药物分析方法不断出现,示波极潜法就是近几年来发展起来的一种新的容量分析方法。该法因操作简便、终点直观、不受沉淀和颜色的干扰以及设备简单、成本低廉、易于掌握等独特优点而在药物分析方面应用越来越广。该法多是采用汞膜电极作极化电极,银棒电极(或铂片电极等)作去极化电极,利用被测物质或滴定剂以及指示剂的示波极潜图的突变(包括切口的
With the rapid development of science and technology, new drug analysis methods are emerging constantly. The oscillometric polar potential method is a new capacity analysis method developed in recent years . The method is more and more widely used in the field of drug analysis because of its unique advantages such as simple operation, intuitive end point, no precipitation and color interference, simple equipment, low cost and easy control. The method is the use of mercury electrode as a polarizing electrode, silver rod electrode (or platinum electrode, etc.) as a depolarization electrode, the use of test substances or titrant and indicator of the oscillometric mutation of the polar map (including the incision of
